Abstract
An apparatus and method for cutting a web of material having a conveyor carrying and continuously moving a length of the web material, an oscillating means, a cutting arm mounted on the oscillating means and moveable between a position over the web and a position laterally outside of the web in a turn-around area. A nozzle mounted on the cutting arm and connected to a source of high pressure fluid and a fluid jet ejected from the nozzle towards the web and moved by the cutting arm in an oscillating manner along a path between the turn-around area and the position over the web. As the fluid jet oscillates along its path, the movement of the fluid jet in conjunction with the movement of the web results in the cutting out of a section of the web.
